What does error 3 on my microlife blood pressure monitor

For most Microlife blood pressure monitors, the error 3 indicates that the unit cannot reach the proper pressure in the cuff to start the test. If replacing the batteries doesn't work, check that the cuff is properly plugged into the socket on the monitor. Next you may need to replace the cuff. There may be a leak in the cuff or the hose between the cuff and the socket. Microlife sells replacement blood pressure cuffs here: https://www.microlife.com/consumer-products/blood-pressure/cuffs-and-supplies . These cuffs fit all of their devices except for the wrist versions.

I hope this helps.

See page 1 of the manual above with phone numbers to call for whatever country you live in and ask you question. There was not an error 4 in this manual. You might want to call your Doctor's office, and inquire. Perhaps batteries are going bad.

Turn it off, Hold down the "M" button until "CL" appears and press "M" while "CL" is flashing.

Several of the CVS brand blood pressure monitors are made by MicroLife USA. For those models, the Error 3 indicates that you may have been moving your arm while the unit was obtaining the readings. You need to repeat the measurement while staying still.

The other possible cause of the error are that the cuff didn't inflate in a reasonable length of time. Check that the cuff is properly placed on your arm. Also make sure that the inflation hose is tightly connected to the cuff socket on the unit.

I hope this helps.
